Beschreibung
China blue lactose agar is a non-inhibitory standard culture medium for the differentiation and colony count determination of bacteria in milk. Originally formulated by Brandl and Sobeck-Skala, this dehydrated medium enables laboratories to count and differentiate bacteria in dairy products with a clear visual readout. China blue in the medium acts as a pH indicator, distinguishing lactose fermenters from non-lactose fermenters on the same plate. Because the formulation contains no inhibitory substances, organisms present in a milk sample grow luxuriantly and give a representative picture of the microbial flora. Supplied as dehydrated powder in a 500 g pack from manufacturer Altmann Analytik, the product corresponds to the Thermo Scientific Oxoid China Blue Lactose Agar line used in dairy microbiology. Typical applications include routine quality control of milk and milk products where both enumeration and lactose-based differentiation are required. The medium supports standard plate-count workflows without selective pressure, making it suitable whenever comprehensive recovery of bacterial colonies from dairy matrices is the analytical goal.
This article is part of Carbohydrates & sugars, in Biochemicals & reagents.

Questions about China Blue Lactose Agar (Dehydrated)
What is this article?
China Blue Lactose Agar (Dehydrated) is the article on this page. Luminix Health distributes Altmann Analytik for laboratory use. It sits in Carbohydrates & sugars, inside Biochemicals & reagents, in Mikrobiologie.
A carbohydrate reagent is a sugar or a derivative, specified by identity, anomer where it matters, and purity. Hydrate and anhydrous forms change the mass. A culture-grade sugar and an analytical standard of the same name are different bottles.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
